摘要：Mobile Ad-Hoc Networks (MANET) constitutes a group of wireless mobile nodes that transmit information without any centralized control. MANETs are infrastructure-less and are dynamic in nature that is why; they require peremptorily new set of networking approach to put through to provide efficacious and successful end-to-end communication. Therefore, an efficient routing approach is needed in MANETs for changing network conditions such as the size of network and partitioning of network. A large number of protocols proposed for MANETs such as DSDV, WRP, CGSR, AODV, CBRP, TORA, ZRP, ZHLS etc. Based on the recent surveys on performance comparisons of all these protocols, it has been seen that the performance of AODV was very good in all network sizes and it performs better in dense mediums and with faster speed. Recent researches on AODV have also figured out that the route repair scheme of AODV needs modifications to make it highly robust protocol for MANETs. This paper gives a modification on local repair of route/link in AODV, if it is broken during communication for MANET and proposes a new route repair scheme namely SI-AODV in order to make up the deficiency of the existing route repair scheme in AODV. The improved route repair scheme concerns about the over head requirement control overhead and end to end delay in transmission. In this improved scheme, nodes are required to keep the next two-hop node address for each route entry in routing table. During route repair, the repairing node use Swarm Intelligence for finding new route for next to next node in the link using ANT based packet forwarding. This ANT based approach will give significant reduction in overhead. The proposed protocol will be highly adaptive, scalable and efficient and mainly reduces endto-end delay in high mobility cases.
